Latest Climate history Stories
Skeptics of global warming regularly point to the fact that average global temperatures have been relatively steady over the past 15 years and a new study may have found a major reason why: small volcanic eruptions.
When fossil fuels are burned, other climate-forcing gases are produced in addition to long-lasting carbon dioxide.
In a study published today in PNAS, Dr William Roberts of Bristol's School of Geographical Sciences and colleagues use computer models to simulate a Heinrich event in Hudson Bay, Canada, adjusting the models to consider freshwater influx only, changing ice sheet height only or both factors together.
Climate change is a global phenomenon, yet Earth scientists are keeping a wary eye on one place in particular - the Arctic.
As the massive ice sheet that once covered much of North America began to melt, icebergs and meltwater would have regularly reached South Carolina and even Florida, according to new research published in the current advance online edition of the journal Nature Geosciences.
Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map sea ice extent in the late 1970s.
New research by the Lawrence Livermore National Laboratory suggests global ocean warming has been underestimated by 24 to 58 percent.
Water expands as it gets warmer and climatologists have suspected that warming in the deep ocean may add to rising sea levels around the world. However, a new study has found evidence that the deep ocean is not warming measurably.
Current changes in the ocean around Antarctica are disturbingly close to conditions 14,000 years ago that new research shows may have led to the rapid melting of Antarctic ice and an abrupt 3-4 meter rise in global sea level.
Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...
The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...
